Specification of Letters Patent.

Application tiled January 10, 1910. Serial No. 537,236.

To all whom, it my mami;

Be it known that I, JACKSON B. YOUNG,

Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Apparatus for Aerat-ing Liquids, of which the following is a specification.

My invention `relates to the class of apparatus for aerating liquids, more commonly employed for carbonating water.

The chief object of my invention is to provide an apparatus of this type which will be operative tor desirable results, regardless of -the Water pressure, and in which the impregnation is eifected by the pressure ofthe gas alone, which'pressure may be regulated to, suit individual taste inthe commodity furnished.

hereinafter, be noted.. y

My invention consists 1n thenovel construction and arrangement of the apparatus which ll shall now fully describe, by reti' erence to the accompanying drawings, in Which- Figure 1 is an elevation of my apparatus, partly in section. Fig. 2 is a broken sectional elevation of the same, to show the valves. Fig. 3 is ay horizontal section of the two jars. 1 is a stand upon which is supported two receptacles or containers, which, from their functions, I may properly term the chargl ing jar 2 and the dispensin jar 3. These may be madey of .any suita le shape and material, though I have here shown them as made of glass, which in addition to sanitary value, adds some attractiveness, as well as interest in the visible operations. p

' lrhe charging jar 2 is suitably secured, to

a base casting 4, in which is made a port 5 y opening through the topy of the casting into the jar, as seen in Fig. 2. The other end of said port opens through the side of the casting, and has fitted to it the inlet pipe 6, Fig. l, which is supposed to lead `from any source of water. i

The port 5 is controlled at its upper end by an upwardly moving valve 7', the stem 8 of which passes down through a suitable fluid-tight packing 9, and carries a foot 1,0, and a spring 11, the latter holding the valve normally closed.

12 is a shaft, rotatably by a lhandle 13. Thisv shaftcarries a number YYof cams, one of which, 1 4, operates `under the steIn-foot 10,.,

v to, lift and open thevalve 7, as is indicated f in Fig. v2. f a citizen of the United States, residing at Opening downwardly from jar 2 throu h it base 1s a assage 15, seen in Fig. 3. o

l 20. of the dipensing jar 3, and thence leads through sai casting, as shown in Fig. 2, and opens into the jar 3. The upper end of this p,ort19 is controlled by an upwardly `'moving valve 2,1, the stem 22 of which passes down through a suitable fluid-tight packing at 23:, and carries a foot 24 and Spring 2 5. A cam 26` on the shaft 12 oper- Y ates under the foot 24, to lift the valve 21. M any other objects of my invention will, 5

In lthe base .casting 4 of jar 2 is made a just above and is adapted to discharge its gas downwardly into the outlet passage 15,

as seen in Fig. 3. The injector'nozzle has a small hole 28 made through its wall, to admit some of the gas directly into the jar 2. rIhe outer end of this port 27 opens through the side of the base casting and has fitted to it, as shown in Fig. 1, a pipe 29 which may be supposedto lead *from any source, of gas under pressure.

The port 27 is controlled by a valve 30 which moves upward to its seat, as shown in Fig. 2, and saidvalve has a stem 31 which passes down through suitable iuid-tight packing at 32 and has a controlling sprin 33.. rlhe lower end of the stem 31 is litte i with a cam-yoke 34, within which operates a cam 35 on the cam-shaft 12.

In the base casting 20 of jar 3 is made a port 36, the upper end of which opens into said jar, as seen in Fig. 2, and the outer end 'has connected with it a delivery pipe 37 as shown in Fig. 1; The upper end of port 36 is controlled by an upwardly opening valve 38, the stem 39 of which passes down l through a suitable fluid tight packing at 40, 'and carries a foot 41 and a controlling spring 42. A cam 43 on the cam shaft 12 operates under the foot 41, to open the V valve 38.

In the base-casting 4 of jar 2 is made a vent-port 44, the upper end of which is fitted with a vent-tube 45 which, as shown in jFig.l 1, extends upward in jar 2, to. near its top. The upper end of this vent-tube is controlled bya downwardly seating valve 46 which is upon a stem 47 passing down through the tube and through the port 44. The lower end of this stem is operated upon by a cam 48 on the cam shaft 12. This cam, as shown in Fig. 1, has a curved side, against which the end of the stem impinges, and rests upon the shaft itself as seen in Fig. 2, thereby keeping the valve 46 closed during a ortion of the time. A small spring149 puls the stem, the end of which is suiiiciently flexible, over in a guide 50, in position to be raised by the cam durin the other portion of the revolution as will be more fully described hereafter.

`vIf Water under sufficient initial pressure is introduced to jar 2, no other venting provision need be made, but where the incom; ing water is under no appreciable ressure, then I insert afloat 51 in jar 2, an connect its arm 52 with the valve 46, so that the weight of the float, while the jar is filling will hold valve 46 open, to permit the air to escape, and said float will close the valve when the jar is filled, in the usual manner of such devices. The outer end of ,the 1vent port 44 has connected with it a vent pipe 53, Fig. l, which opens to the outer atmosphere.

In the base-casting 20 of -jar 3 is made a port 54, the upper end of which has con nected with it a vent tube 55 which rises, as seen in Fig. l to near the top of the jar 3. The lupper en of this tube is controlled by a valve 56, the stem 57 of which passes down, as seen in Fig. 2, through said tube and through the port 54. It is suitably packed at 58 and carries a foot 59 and a controlling spring 60. VA cam 61 on the cam-shaft 12 operates under foot 59 to lift the valve 56. The outer end of port 54 has fitted to it a vent-pipe 62, as seen in Fig. 1, which opens to the outer atmosphere. 63 in Fig. 1, is the ordinary si hon valve discharge, fitted to .jar 3. T is may or may not be employed, and if present, is used only in case one desires to have the carbonated water delivered under pressure, instead of by gravity only, or it may be used to iill the ordinary Seltzer-bottles.

In Fig. l, the mixer 17, heretofore mentioned may consist of any suitable channel which by breaking up the lines of flow will cause a more perfect impregnation of the liquid with the gas. In the present case, I deem the form here shown a novel and advantageous one. It consists of a tube, or shell traversed at intervals by disks of two constructions. One, designated by 64 is centrally perforated by' a relatively large hole; the other, 65 is -formed with an annular series of relatively small holes, disposed near its periphery. These two constructions alternate, as shown, and are held 'in place by intervening sleeves 66. The course of flow is thus an interrupted, tortuous one, which results in an intimate mixture of liquid and gas. A more or less similar result may be had by lengthening and rendering more tortuous the pipe co1l 18, in which case the mixer proper may or may not be employed.

The apparatus havin now been fully described, tne following escription of its o1?- eration will be understood.

It may be stated, at the outset, that'pressure of the water isnot to be essentially considered. The water may or may not be under pressure asis ordinarily understood in this art. It need be under head only suicient to flow into the charging jar 2. The

ressure ofthe gas may be reduced to any egree, according to the taste of the user. If a sharper aeration be required the pressure of gas has' only to be increased. Let us suppose, then, that the pi e 6 be connected with any source of Water ow, whether from a spring, a tank, a city-main, or other delivery of water; and that the pipe 29 be connected with a flask or tank of compressed gas, reduced by a regulator to any working pressure. Suppose now the cam-shaft 12 be turned so that the valve 7 will be lifted. The water will now flow, under whatever head it may have, into the charging jar 2; and, because, the ioat 51 is holding the air vent valve 46 open, the jar will fill with the water no matter how low its pressure may be. If, however, the water be under Sullicient pressure to compress the air in jar 2 without an air vent while filling, it will be seen that, as I have heretofore stated, the oat may be omitted, and the vent valve 46 remain closed while lling. But,'continu ing the operation, with the presence of the loat, the jar 2 will fill, until stop ed by the iioat. We have now, the jar 2, Elled with water, and the air vent 45- closed. Now a further movement of the cam shaft 12 will cut oif the incoming water, and open the valve 30 to the as -from pipe 29. At the same time, it will open the valve 21 in the dispensing jar 3. Thereupon the gas ,injected through the nozzle 28 into the passage 15 will, by injective suction, assisted by the as pressureadmitted through its small gole 28 carry the water with 1t, so that the Water will be forced under pressure of the gas out of the jar through the passage 15 through the pipe 16, the mixer 17 and the pipe coil 18, 1n all of which the water and gas will be mixed and carbonated and up past the open valve 21 into the dispensing jar 3, and fill said jar with the aerated water. The apparatus is now ready for continued use. To draw the aerated Water from the dispensin jar 3 the cam shaft is again turned. This has certain simultaneous effects, and both jars are relieved offv pressure as follows Valve 21 is closed and entraps the aerated water in the dispensing jar 3,

and the vent valve 56 in said jar is opened and the compressed air is exhausted through vent at the same time as valve 30 1s closed and vent valve 46 in c arging jar 2 is opened by cam 48 and the gas 1s exhausted through pi e 53 so that said chargingjar may be re lled with fresh water. hen when both of said jars shall have been relieved of the air and gas pressure, another slight turn of cam shaft 12 roduces two other simultaneous effects, tow1t1-Valve 38 in dispensing jar 3 is opened and the aerated Water, under no pressure other than its own head, is drawn out by gravity and without undue agitation which is of advantage 1n the quality of the commodity furnished; and, at the same time, valve 7 in charging jar 2, is opened, and said jar, havlng been relieved of its gas pressure, is refilled with fresh water. By the time the aerated water in jar 3 is delivered, the charge of fresh water in jar 2 is complete, and, thereupon, the further movement of the cam shaft, stops both delivery and dischar e, and opens the gas connection to imme iately cause the water and gas to proceed again through the mixer and pipe coil and once more -fll the dispensing jar. m

As before stated, the aerated water may be delivered under pressure throu h the siphon delivery 63 if desired; but th1s is not best, as the water is of improved quality if allowed to flow `with minimum disturbance, under its own gravity head. i

I thus provide a simple and inexpenslve machine for laerating water or other liquids from any supply, regardless of water pressure, by means of the pressure of the gas which is used to carbonate the water, and I thus dispense with any `other pressure or machinery. j i

This apparatus will aerate water from springs or other locations .without regard to pressure, or where a filter is placed in the water supply pipe, which takes away' or diminishes whatever pressure mayexist. `Pro.

vision isV also made for relieving pressures without 'agitating `the aerated water, and then drawing it olf by its own gravity. By the siphon arrangement a foaming beverage may be had if desired. The arrangement of the valves, here shown, which lift from their seats and return again without rubbing -or wearing action such as occurs with a plug-valve is especially desirable in this class of apparatus.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1.
